Amygdala activity

Remember the end of the FedEx ad, when the caveman is crushed by the dinosaur? Researchers looked at the activity in the amygdala, a tiny brain structure critical for emotional processing in general, especially responding to threat and fearful stimuli.

This scan shows a big jump in amygdala activity when the dinosaur crushes the caveman. The scene looks funny and has been described as funny by people who watched it, but the amygdala still perceives it as threatening, another example of the disconnect between verbal reports on ads and brain activity while viewing them.
